I notice sometimes that the thread is unwinding as I tie. What I mean is that the tying thread itself starts to look more like floss--the individual strands become visible as the twist in the thread is removed. I strongly suspect that this is because I am left-handed and the thread is laid (twisted) clockwise, yet the action of tying left-handed is counter-clockwise so it unwinds the thread. Is this what I am seeing? Is it a problem? If so, is it better to reverse how you wrap the thread, or just to learn to tie right-handed? Hopefully this is not a serious problem and I can just keep tying and unraveling the thread as I do it, but if it's going to noticeably compromise the fly, I should relearn now rather than after the habits are ingrained. At my work, I have to do everything right-handed because ropes are made the same way.
